NGSS.HS-LS4-3

A population of 150 individuals has an allele frequency of 0.3 for the dominant allele (B) and a frequency of 0.7 for the recessive allele (b). Use the Hardy-Weinberg equation to determine the frequency of the genotype (bb).

• 0.09
• 0.42
• 0.49
• 0.21

Which DNA strands move the fastest through the agarose gel when electricity is applied?

• long strands

• short strands

• medium strands

• They all move the same

The purpose of PCR

• cutting DNA
• creating RFLPs
• amplifying/copy DNA
• reversing the charge of DNA

What is the charge of DNA?

• positive
• negative
• neutral

On an electropherogram, alleles are represented by...

• peaks on a graph

• letters like AA or Aa

• blue dots on a test strip

• band on an autorad

If there is only one allele (one peak) on the electropherogram for a particular locus, what does that tell you about the genotype?

• the genotype is heterozygous

• the genotype is codominant

• the genotype is homozygous

• the person did not inherit any allesl for that STR loci
